A pipe joint is a connecting tool between pipelines, which is a detachable connection point between components and pipelines. It plays an indispensable role in fittings and is one of the two main components of hydraulic pipelines. Pipe joints are used for straight connections such as instruments, and the connection forms include socket welding or threaded connections. Mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or for adjusting pipelines using threaded fittings. The structural form should adopt a metal surface contact sealing structure, and the gasket sealing structure is usually used for conveying general pipelines such as water, oil, and air, and is made of malleable cast iron material. In addition, usage requirements and price are also factors considered when selecting.
There are various types of pipe joints, and commonly used pipe joints can generally be divided into two types: hard pipe joints and flexible pipe joints. If classified according to the connection method of pipe joints and pipelines, there are three types of hard pipe joints: expansion type, sleeve type, and welding type, while hose joints are mainly compression type rubber hose joints.

The connection methods of pipelines and pipe joints in hydraulic systems are also different, and the threaded end of the pipeline is used for connection. Cone threads, relying on their own vertebral body to tighten and sealed with materials such as polytetrafluoroethylene, are mainly used in medium and low-pressure hydraulic systems. The sealing effect of fine thread is very good and is often used in high-pressure systems. However, it requires the use of combination washers or O-rings to seal the end face. Sometimes, copper washers are also used, which are more suitable for connecting pipes with thick walls. Its main components are the joint body, connecting pipe, and nut. When in use, embed the joint body into the target and use the gasket mentioned earlier to seal the end face. Rubber sealing is used between the joint body and the connecting pipe, and sometimes spherical sealing is also used.
Due to the fact that pipe joints are detachable connecting components, they not only meet the requirements of stable connection, strong sealing, reasonable size, low pressure loss, good process performance, etc., but also need to meet the requirements of convenient disassembly and assembly. Therefore, do not underestimate those small pipe joints, because only their existence can support the existence of the entire hydraulic system.
